Hardly a surprise given its chemistry;

Is this likely to lead to restrictions on its use in analytical labs ?

Peter, given how long it took the world to restrict CFCs, I suspect we'll be long-since retired before MeCl2 is restricted. You can still buy R22 Freon today, a couple of decades after its use was discontinued in auto air conditioners.

In any case, analytical sample prep is only a drop in the bucket (okay, bad analogy) compared to the use of MeCl2 in industrial processes.

I see that its atmospheric concentration is slowly increasing:
